The brightness controls on my laptop wont work after an upgrade to Windows 10.
In addition, the brightness slider in the Power Options control panel is also missing.
I have ran and installed the drivers from Dell, using the Dell Detect app, but still nothing.
Any ideas?
I got the exact same screen when I ran
powercfg /l
